CENTRIFUGAL CREAM-SEPARATOR.

SPECIFICATION formingpart of Letters Patent No. 782,167, dated February 7, 1905.

Application filed December 8. 1903. Serial No. 184,319.

To a who! it nut/ (WU/(1677b:

Be it known that I, KENNETH K. MoLnoo, a citizen of the United States,residing at Sparta, in the county of Monroe and State of \Visconsin, have invented new and useful Improvements in (,ream-Separators, of which the following is a specification.

My invention relates to new and useful improvements in cream-separators; and its ob ject is to provide a simple, compact, and inexpensive device of this character having mechanism whereby the bowl of the device can be rotated. said mechanism being so arranged as to be conveniently operated manually.

Another object of the invention is to so arrange the parts of the device as to permit the milk-tank to be located at such an elevation as to be readily reached for the purpose of filling the same.

\Yith the above and other objects in view the invention consists of a casing preferably formed of sheet metal and having a tank detachably mounted thereon. This tank has an outlet located above the revolublc bowl, and motion is transmitted to the bowl by means of mechanism located within the casing.

The invention also consists in the novel construction, combination, and arrangement of parts, as hereinafter fully described, illustrated, and claimed.

ln the accompanyingdrawings, Figure l is a side elevation of the separator with the faceplate removed and the front plate shown in plate has a hollow forweirdly-extending portion 7, in which is revolubly mounted a rod 8, the lower end of which isjournaled in a bearing 9 provided therefor, while the upper end projects through the top of the projecting portion 7 and into a casing 10. A bowl 11 is rcvolubly mounted within the casing and is secured to the rod 8. A worm 12 is secured to the rod at a point within the extension 7 and meshes with a worm 13, arranged on a shaft 1%.. A sprocket 15 is also secured to the shaft and receives motion from a large sprocket 16 through a chain 17. The sprocket 16 is socured to a shaft l8, journaled in the side plates 3, and has a smaller sprocket 19, on which is arranged a chain 24), which extends over a sprocket 21 and connected to a shaft 22. This shaft is journaled within the side plates 3 and has a crank 23 secured to it, whereby the same may be readily rotated. A bracket 2st is secured to one of the side faces 3 at a point slightly above the shaft 22, and this bracket serves to support a tank 25, having a faucet 26 at one end thereof and above the bowl ll. It will be seen that by arranging the tank in this manner the top thereof is brought adjacent to the top of the gear 21, and therefore milk can be readily poured into the tank. Small crank-shafts 27 are journaled within the side plates and have idlers 28 thereon, which are adapted to bear upon and tighten the chains 17 and 20.

It is thought that the operation of this device will be thoroughly understood from the foregoingdescription,taken inconnection with the accompanying drawings. By turning the crank 23 motion is transmitted to the worms l1 and 12, and the bowl is thereby rotated within the casing l0.

All of the parts are within easy access and the working portions of the mechanism are protected from dust, 842., and are therefore more lasting. By means of the idlers arranged on the crank-shafts 27 the wear upon the chain and sprockets can be taken up. 'lhese crank-shafts can be locked in adjusted posi tions in any desired manner, as by means of clamping-nuts 2f) thereon.

In the foregoing description 1 have shown the preferred form of my invention, but do not limit myself thereto, as I am aware that modifications may be made therein withoutdeparting from the spirit orsacril'icing any of the advantages thereof, and I therefore reserve the right to make such changes as fairly fall within the scope of my invention.

Having thus described the invention, what I claim as new is A separator of the character described comprising a base-plate having integral supports, side plates and a rear plate detachably secured to the base-plate and to one another, a front plate detachably secured to the side plate and having a hollow forwardly-extending portion, a rod revolubly mounted in said portion and projecting from one end thereof, a casing inclosing one end of the rod, a bowl revolubly mounted Within the casing and secured to the rod, a worm upon the rod and within the projecting portion, a shaft journaled within the side plates, a second worm secured thereon and meshing with the worm on the rod, a sprocket upon said shaft, an intermediate shaft journaled in the side plates, sprockets thereon and l between the side plates, a chain for transmitting rotary motion from one ofsaid sprockets to the sprocket on the Worm-shaft, a driveshaft journaled within the side plates, a sprocket thereon and between said plates, a chain for transmitting rotary motion from said sprocket to one of the sprockets on the intermediate shaft, means for rotating the driveshaft, crank-shafts secured within one of the side plates, means for clamping them against movement, idlers thereon for engaging and tightening the chains, brackets extending from one of the side plates, and a tank supported upon said side plate and brackets and having an outlet into the bowl.

In testimony whereof Iaflix my signature in presence of two witnesses.
